I am using below method of ADAL iOS library to Acquire access token silently.

acquireTokenSilentWithResource:completionHandler:

But it fails with an error:

ERROR: Error raised: 10. Additional Information: Domain: ADAuthenticationErrorDomain ProtocolCode:(null) Details:The user credentials are need to obtain access token. Please call the non-silent acquireTokenWithResource methods.. ErrorCode: 10.

Any help is appreciated.Tested in both ADAL iOS versions 1.2.1 and 1.2.9.

Can you provide more details about your scenario? Has the user already authenticated once before (so that acquire...Silent can use the refresh token to get a new access token silently)? - Philippe Signoret
yes in my case user already authenticated manually using username and password.But after each 1 hour the access token is getting expired.So I am calling above acquireTokenSilent... method to get new access token. - Shyam
Can you share the code you're using for: "manually using username and password"? - Philippe Signoret
@Shyam did you solved this? am having same problem - Himanth

In order for this method to succeed, there must first be a successful token acquisition. First use: acquireTokenWithResource, the user will be presented with UI for credentials. ADAL will cache the tokens. The subsequent call to acquireTokenSilentWithResource will then succeed (assuming the resource etc. are the same).
